Aligned with 2026-2027 ACSA NCSO certification requirements and Canadian construction safety standards
150 Questions • 9 Sections • Cognitive Mix: 30% Recall, 50% Application, 20% Analysis
Examination Overview
This comprehensive exam preparation resource has been developed to align with the 2026/2027 Alberta Construction Safety
Association (ACSA) National Construction Safety Officer (NCSO®) certification requirements. The NCSO® designation
requires successful completion of eleven compulsory courses, two elective courses, a minimum of three years of
construction field experience within the past ten years, and a passing mark of 75% or better on a closed-book,
online-proctored multiple-choice examination. Candidates are allotted a maximum of two hours to complete the official
examination.
The questions contained in this document mirror the cognitive distribution of the actual NCSO examination: 30% recall of
fundamental safety concepts, 50% application of safety principles to construction site scenarios, and 20% analysis requiring
integrated clinical judgment. Approximately 70% of questions are scenario-based, 20% are direct recall, and 10% involve
calculation of safety performance metrics such as the Lost Time Frequency Rate (LTFR), Injury Severity Rate (ISR), and
Total Recordable Incident Frequency (TRIF). Each question includes a verified correct answer and a comprehensive
rationale grounded in Canadian OHS legislation, COR™ program standards, and ACSA-recognized safety practices.
Section 1: Health and Safety Management Systems (HSMS) & COR™ Program
Elements
Questions 1-25 cover HSMS structure, the 13-element COR™ audit framework, SECOR for small employers, SMART action plans,
prime contractor responsibilities, and the four key management functions (Plan, Organize, Lead, Control).
Q1: A regional civil contractor is restructuring its safety program after a series of recordable
incidents. The safety director explains to the executive team that an HSMS is not merely a binder
of policies but rather "a complete system that maintains high standards throughout every part of
the company's organization." Which statement most accurately reflects the defining
characteristic of a Health and Safety Management System (HSMS) as recognized under the ACSA
COR™ framework?
A. A binder of safe work practices that workers reference when completing high-risk tasks.
B. A documented set of policies stored at the corporate office and reviewed annually by the auditor.
C. An integrated system linking leadership, hazard assessment, training, inspections, investigations, and
evaluation across all organizational levels. [CORRECT]
D. A regulatory requirement imposed exclusively on prime contractors by Alberta OHS legislation.
Correct Answer: C

,ACSA NCSO Exam | 2026/2027 Edition 150 Verified Questions
Rationale:
An HSMS, as defined within the ACSA COR™ framework, is an integrated system that connects leadership commitment, hazard
identification, training, inspections, incident investigation, emergency preparedness, and program evaluation across every
organizational layer. Options A and B describe documentation artifacts rather than a functioning system, while Option D
incorrectly frames HSMS as a legal requirement imposed only on prime contractors; in reality, HSMS adoption is voluntary but
demonstrates due diligence under Canadian OHS legislation.
Q2: A small roofing subcontractor with eight employees is seeking ACSA recognition for its safety
program. The owner asks the NCSO whether the company should pursue COR™ or SECOR.
Which response by the NCSO is correct under the 2026/2027 ACSA program rules?
A. The company must pursue full COR™ because SECOR was discontinued in 2020.
B. The company is eligible for SECOR because it has 10 or fewer employees. [CORRECT]
C. The company must wait until it grows beyond 25 employees before applying for either designation.
D. SECOR is restricted to oil and gas employers and is not available to roofing contractors.
Correct Answer: B
Rationale:
Under ACSA's program structure, the SECOR (Small Employer Certificate of Recognition) is specifically designed for employers
with 10 or fewer employees and provides a streamlined alternative to the full 13-element COR™ audit. Option A is incorrect
because SECOR remains an active ACSA offering; Option C is incorrect because there is no 25-employee threshold; and Option
D is incorrect because SECOR is open to small employers across all construction sectors, not only oil and gas.
Q3: During an internal audit preparation meeting, a junior safety coordinator claims the COR™
program contains 10 elements. The NCSO must correct this misconception. How many elements
are contained in the COR™ program audit structure?
A. 8 elements
B. 10 elements
C. 13 elements [CORRECT]
D. 15 elements
Correct Answer: C
Rationale:
The COR™ program audit structure contains 13 elements, including Management Commitment and Leadership, Hazard
Identification and Assessment, Accident Investigation Procedures, Worker Training, Emergency Preparedness, Health and Safety
Program Administration, Worksite Inspections, Joint Health and Safety Committee, Corrective Actions, Contractor Management,
Safe Work Practices and Procedures, Workplace Health Promotion, and Program Evaluation. The 10-element figure is a common
exam distractor that confuses the COR™ structure with other provincial frameworks or with SECOR's reduced scope.
Q4: A site safety coordinator is drafting an action plan to reduce scaffold-related incidents over
the next year. The plan states: "Improve scaffold safety," with no measurable target, no deadline,
and no assigned owner. According to ACSA COR™ action plan guidance, which SMART element
is MOST critically missing from this objective?
A. Specific, because "improve scaffold safety" lacks a precise outcome.
B. Measurable, Attainable, Relevant, and Time-bound are all simultaneously missing. [CORRECT]
C. Time-bound, because no completion date is identified.
D. Attainable, because the goal may exceed available resources.
Correct Answer: B

,ACSA NCSO Exam | 2026/2027 Edition 150 Verified Questions
Rationale:
The SMART acronym requires that every action plan objective be Specific, Measurable, Attainable, Relevant, and Time-bound.
The statement "Improve scaffold safety" fails all five SMART tests simultaneously: it is not specific (no precise outcome), not
measurable (no metric), not attainable as written (no defined resource plan), not clearly relevant (assumed but unstated), and not
time-bound (no deadline). While Option A and Option C identify individual failings, the BEST answer recognizes that all SMART
elements are missing, which is the comprehensive deficiency the NCSO must address.
Q5: On a large multi-employer commercial build, the prime contractor has asked each
subcontractor to submit a Project Safety Plan before mobilization. Which statement BEST
describes the purpose of the Project Safety Plan within the HSMS framework?
A. It is a regulatory document required by Alberta OHS legislation for every construction project over $1 million
in value.
B. It is the guiding document for each employer on site participating in the HSMS, identifying hazards, controls,
training, and emergency procedures specific to that employer's scope of work. [CORRECT]
C. It is a duplicate of the prime contractor's corporate safety manual submitted for record-keeping purposes
only.
D. It is a billing document used to recover safety administration costs from the project owner.
Correct Answer: B
Rationale:
The Project Safety Plan is the guiding document for each employer on site participating in the HSMS, identifying site-specific
hazards, controls, training requirements, and emergency procedures relevant to that employer's scope of work. It is not legislated
(Option A is incorrect), it is not a duplicate of the prime contractor's manual (Option C is incorrect), and it has nothing to do with
billing (Option D is incorrect). The Project Safety Plan operationalizes each employer's HSMS at the worksite level.
Q6: A heavy civil contractor is mobilizing to a greenfield industrial site. The prime contractor has
issued a project-specific environmental management plan but expects each subcontractor to
participate. Under COR™ Element 10 (Contractor Management) and the prime contractor's overall
HSMS obligations, what is the prime contractor's primary responsibility regarding environmental
management on a multi-employer site?
A. Delegate all environmental responsibility to individual subcontractors and retain no oversight.
B. Develop a collaborative environmental management program that coordinates subcontractor participation and
ensures integrated site-wide environmental controls. [CORRECT]
C. Avoid environmental planning until an incident occurs to minimize documentation burden.
D. Restrict environmental management to spills of hazardous materials regulated under TDG only.
Correct Answer: B
Rationale:
Under the COR™ framework, the prime contractor is responsible for developing a collaborative environmental management
program that coordinates subcontractor participation and ensures integrated site-wide environmental controls. Option A
incorrectly absolves the prime contractor of oversight; Option C is reactive and inconsistent with due diligence; and Option D is
too narrow because environmental management extends beyond TDG-regulated materials to include erosion control, dust, noise,
wildlife, waste, and other impacts.
Q7: A newly promoted construction superintendent is preparing for a COR™ internal audit. The
auditor asks the superintendent to identify the four key success factors for management as
defined in the Principles of Health & Safety Management course. Which set of factors is correct?
A. Plan, Organize, Lead, Control (POLC) [CORRECT]
Complete and Accurate Page 3 Canadian Construction Safety Standards
, ACSA NCSO Exam | 2026/2027 Edition 150 Verified Questions
B. Predict, Operate, Learn, Communicate
C. Prepare, Observe, Listen, Correct
D. Plan, Outsource, Leverage, Comply
Correct Answer: A
Rationale:
The four key success factors for management, as taught in the ACSA Principles of Health & Safety Management compulsory
course, are Plan, Organize, Lead, and Control (POLC). These functions form the management cycle that sustains an effective
HSMS: planning establishes objectives, organizing allocates resources and assigns responsibilities, leading engages workers and
reinforces culture, and controlling measures performance and applies corrective action. Options B, C, and D are distractor
constructions that resemble the acronym but do not reflect ACSA course content.
Q8: During a leadership review, the NCSO observes that the company president has signed the
safety policy but has not allocated budget for training, has not attended a single JHSC meeting in
18 months, and has not participated in any safety walk-throughs. Which COR™ element is MOST
deficient in this scenario?
A. Element 2: Hazard Identification and Assessment
B. Element 1: Management Commitment and Leadership [CORRECT]
C. Element 9: Corrective Actions
D. Element 13: Program Evaluation
Correct Answer: B
Rationale:
Element 1 (Management Commitment and Leadership) is the most deficient because the president has signed the policy but has
not demonstrated active leadership through budget allocation, JHSC participation, or visible safety engagement. Management
commitment under COR™ requires more than a signed policy; it requires visible, active involvement and resource allocation.
While Elements 9 and 13 may eventually be affected, the root deficiency is leadership commitment, which propagates weakness
throughout the entire HSMS.
Q9: A contractor's annual COR™ audit identified seven gaps in the health and safety program.
The NCSO is preparing an action plan to address these gaps. According to ACSA guidance, what
is the primary purpose of the action plan?
A. To document audit findings for legal protection in case of a regulatory inspection.
B. To improve the HSMS over the upcoming year by assigning SMART objectives, owners, and deadlines for
each identified gap. [CORRECT]
C. To penalize supervisors whose areas were found non-compliant during the audit.
D. To replace the existing HSMS with an entirely new safety program each year.
Correct Answer: B
Rationale:
The primary purpose of an ACSA action plan is to improve the HSMS over the upcoming year by establishing SMART objectives
with assigned owners and deadlines for each gap identified during the audit. Option A mischaracterizes the action plan as a legal
defense document; Option C incorrectly frames it as a punitive tool; and Option D misunderstands the action plan as a wholesale
replacement of the HSMS, when in fact it is an iterative improvement mechanism built on existing program foundations.
Q10: An electrical subcontractor employs 11 full-time electricians and 4 part-time apprentices, for
a total of 15 employees on the payroll. The owner believes the company qualifies for SECOR
because the apprentices are "part-time." Which response by the NCSO is correct?
